For aerobic respiration to take place within the mitochondria, the final product of glycolysis, pyruvate:
| 1. | is transported from the cytoplasm into the mitochondria. |
| 2. | undergoes oxidative decarboxylation in the cytosol. |
| 3. | is reduced to lactate in liver. |
| 4. | is transported from the cytoplasm first into the Golgi apparatus, where it is packaged and then transported into the mitochondrion. |

Pyruvate, which is formed by the glycolytic catabolism of carbohydrates in the cytosol:
| 1. | undergoes oxidative decarboxylation in cytosol itself by a complex set of reactions catalysed by pyruvic kinase. |
| 2. | undergoes reduction in cytosol itself by a complex set of reactions catalysed by pyruvic dehydrogenase. |
| 3. | undergoes oxidative decarboxylation in mitochondrial matrix by a complex set of reactions catalysed by pyruvic dehydrogenase. |
| 4. | undergoes oxidative phosphorylation in mitochondrial matrix by a complex set of reactions catalysed by pyruvic decarboxylase. |
